Keratin - based materials in Biomedical engineering

A biomaterial is used to replace tissue or its function within the living body. Many natural occurring polymers like collagen, fibrin, elastin, gelatin, silk fibroin, hyaluronic acid and chitosan, that have been broadly utilized as in biomaterial applications. In addition to this, proteins are known to be used as one of the popular biomaterials because of their capability to work as synthetic ECM. Among this, keratin is a protein used as effective biopolymers in the fabrication of many new biomaterial(s). Various new techniques have been made for their extraction and structural characterization. Keratin is being characterized as repetitive sequences of amino acid that led in the production of self-assembly. The self-assemble character of keratin has attained to develop into many physical appearances such as sponges, nano-particles and films, found helpful in many drug deliveries and biomedical tissue engineering. This manuscript detailed the advanced utilisation of keratin biomaterials in the area of tissue engineering; wound healing, drug delivery, and so on.
